In the developed world, buildings are responsible for:

• consuming over 70% of the electrical power generated

• consuming 40% of primary energy

• 40% of CO2 emissions from combustion

Joint Task Force on Energy Efficiency Standards in Buildings: Planned Activities

a) Mapping energy efficiency standards in buildings and preparing gap analyses

b) Evaluating options for the development, adoption or promotion of energy efficiency standards in buildings

c) Preparing guidance materials

d) Promoting partnerships with other international organizations

e) Establishing a network of experts on ee in buildings

f) Developing and organizing training programmes

Framework guidelines for EE standards in buildings

Energy required by buildings can be supplied largely, perhaps exclusively, by non-carbon-based energy

Principles

Strategic – Buildings must be:

Science-based: design, construction, and management

Financed through policies recognizing the value of better buildings

Service-oriented: meet the sustainability demands of the populations served

Integrated with their built environment life-cycle to connect buildings as

energy generators and consumers

Cost effective to mobilize private investment and entrepreneurs

Performance-monitored with feedback loops to operations and design tools

Performance-based: evaluated by system outcomes, not component

prescriptions

ENERGY

Principles

Design and Construction –

Conception/delivery of buildings must be: Holistic and integrated: recognize buildings and their environment are part of a

system.

Affordable: high performance buildings costing the same as or less than in 2016

Validated: based on energy models that reliably predict actual building performance

Sustainable: made using sustainable materials, equipment, construction,

management and retirement practices

Code-driven: with local adaptation of global building standards

Skills based: develop work-forces to provide technology/skills needed for design,

construction and operation

ENERGY

Principles

Management – Building must be

maintained over their life-cycle: Commissioning: With commissioning and re-commissioning of active systems

Performance-based: With on-going benchmarking, monitoring & reporting of

performance data

Certification: Maintain certification or labelling to ensure energy performance is

incorporated in to asset value

Managed: professionally managed large or complex buildings with ethos of

sustainability & social responsibility

Data-linked: with advanced building information management capacity, where

public infrastructure permits

Evaluated: On going performance evaluation and improvement

City-scaled: information analysis and outcomes

Life cycle-based: with long term analysis
